Simultaneous operation of NFC, Bluetooth and wireless charging

I have a question - the idea was born to make a contactless cradle for the phone in the car. The idea is this - we lower the phone into the slot, there is wireless charging on the back panel, and on command from NFC, bluetooth should turn on. The catch is, I believe that wireless charging will jam Bluetooth and even more so NFC. Does anyone have positive or negative feedback on the simultaneous operation of these systems?
PS There is a car charger from Nokia - Nokia CR-200, just wireless and with NFC, but it is put on a separate "leg" and it needs to be touched separately before charging.

Qi charging frequency = 100~200 kHz
NFC frequency = 13.56 MHz
Bluetooth frequency = 2.4 GHz
These are different frequency ranges, the wavelength differs by orders of magnitude, etc.
What in practice:
And try to put an NFC card directly on a wireless charger, for example, a used one-time ticket from the Moscow metro, and consider it a phone that supports NFC and Qi. Right now I don’t have the opportunity to conduct such an experiment, but I will also try it for a couple of days and write back here.

select t0.* from `table` as t0
inner join `table` as t1
    on t1.id = t0.id + 1 and t1.level = t0.level + 1;
